Diggin for Diamonds The Big Bonanza: Slot Overview
If blasting your way through underground tunnels is your idea of a good time, Yggdrasil Gaming partner Jelly offers another chance to do exactly that. The slot is Diggin for Diamonds The Big Bonanza, and it also suits anyone craving a scatter-paying slot where multiplier symbols land on the grid and their values can stack up during free spins. It may already sound somewhat familiar, but let’s keep an open mind, strap on the hard hats, and head down the shaft to see how Diggin for Diamonds The Big Bonanza handles the mining gig.
Before the digging begins, Diggin for Diamonds The Big Bonanza sets the scene above ground at a mine entrance in a rugged, rocky landscape. A bundle of dynamite sits a little too close to the tracks, and you’re joined by a beaded miner (featured on the wild symbol) — the kind of character that nearly always turns up in a game like this. Honestly, if slot games are anything to go by, anyone hoping to make it in mining had better arrive with some seriously impressive facial hair. A light banjo-led Western jingle plays in the background, and while the visuals are agreeable enough, the overall vibe does lean a bit generic.

If you’re still on board, you can choose a wager of 20 c to $/€80 per spin and start drilling. Jelly rates Diggin for Diamonds The Big Bonanza’s volatility as high, and it comes with multiple RTP configurations, topping out at 95.1%. Gameplay runs on a 6-reel, 5-row grid and uses a scatter-pays approach to award wins.
The way it works is simple: when 8 matching pay symbols appear anywhere on the reels, a scatter win is formed. There are nine standard paying symbols — 5 different gems, plus a drill, a lantern, a cart of gems, and a miner. An 8-symbol hit returns 0.25 to 10 times the bet, while a 12+ symbol scatter win pays 2 to 50 times the bet. Diggin for Diamonds The Big Bonanza doesn’t include any wilds, though it does feature a scatter and a multiplier symbol. A tumble mechanism removes symbols that formed winning scatters and replaces them with new ones dropping in from above. Tumble chains stop once a tumble produces no additional win.
Diggin for Diamonds The Big Bonanza: Slot Features

Alongside the base gameplay, there’s a free spins round, modifiers, two bonus buys, and a Gold Bet. Here’s what each one does.
Multiplier Symbols
Diamonds act as multiplier symbols, appearing on all reels and showing up in both the base game and free spins. When they land, they carry a value of x2 to x100. Once a tumble sequence ends, the values of every multiplier symbol are added together and then applied to the final win amount.
Modifiers
Keep an eye out for the loss-to-win modifier, which can turn a losing result into either a win or a bonus.
Free Spins
Landing 4, 5, or 6 scatter symbols awards 12, 15, or 18 free spins, respectively. Each time a multiplier symbol appears during free spins, its value is added to the total multiplier for the entire free spins session. That total multiplier is then applied to any wins. If you hit 3 or more scatters during the feature, you receive +5 free spins.
Bonus Buy & Golden Bet
Using the bonus buy, you can purchase 12 free spins for 100x the bet or buy 15 or 18 free spins for 250x the bet. Finally, enabling the Gold Bet increases your stake by 25% to improve your chances of triggering the bonus.

Diggin for Diamonds The Big Bonanza: Slot Verdict
Diggin for Diamonds The Big Bonanza’s tagline reads, ‘Get ready to dig out the diamonds in this epic multiplier based cascading title’ — though in practice, it didn’t really feel all that epic. A major sticking point is how closely it echoes games such as Sweet Bonanza or Gates of Olympus. Pragmatic Play has struck a rich seam with those titles and similar releases, so copycat attention is inevitable — especially in a gambling industry where studios circle proven hits like scavengers, waiting to grab a piece for themselves. Jelly certainly isn’t the only team that might be “influenced” by what works elsewhere, but they didn’t help matters by wrapping Diggin for Diamonds The Big Bonanza’s familiar mechanics in a rather tired theme.
That said, it’s difficult to be overly harsh about a set of features that has already proven its appeal. In Diggin for Diamonds The Big Bonanza, the combination of scatter wins, tumbles, and multiplier symbols can kick off just as readily as it does in other games built on the same formula. However, Jelly doesn’t have the same level of slot-making polish as Pragmatic Play, so Diggin for Diamonds The Big Bonanza lacks some of the big win fanfare and ultra-slick presentation you’d expect from a Prag title — or at least it doesn’t reach that same standard. Where Diggin for Diamonds The Big Bonanza does separate itself from the two games mentioned earlier is in free spins: the win multiplier always applies to wins — multiplier symbols don’t need to be present for the multiplier to take effect. Likewise, you don’t even need to land wins for multiplier symbols to contribute their values to the win multiplier. It’s a more straightforward, less fiddly approach in some respects, and it’s easy to see why some players would prefer it. The review produced a few decent moments, but the max win of 2,864x doesn’t stack up particularly well against what rivals can deliver.
All told, if you’re fine with playing something that feels a bit like reheated leftovers, Diggin for Diamonds The Big Bonanza still has the right components for enjoyable mining-themed scatter wins with additive multiplier action. The max win could have been bigger, though.
